* Have your NAR number or your name on the outside, large
and clear enough that the contest officials can easily read it. Teams must use
the Team number or name. USMRSC 9.4

* Have been constructed by yourself or by one or more
members of your Team. You may not enter Ready-To-Fly rockets (no construction
required) in NAR sanctioned competition. USMRSC 9.9

Know the rules

Your having a grasp of the bigger picture can increase your
enjoyment of NAR competition. You can read the Pink Book Lite to see only
the rules for competitors, not for Contest Directors or other contest
officials. Read the full USMRSC (Pink Book) to see all the rules.

* In Radio Controlled Glider Competition you want to repeatedly achieve specified flight times of your choice, and land as
close as possible to a designated spot consistently over a series of three
flights. USMRSC 62.1

* The duration starts at the first motion on the launch pad
and ends when the gliding portion lands or the timer loses sight it. USMRSC 15.6

* Your final score is the sum of your three official flights.
The contestant with the lowest total error summed over three flights is the
winner. USMRSC 62.5

* The score for each official flight has two parts: Time and
Distance. USMRSC 62.5

Time: Actual Flight Time in seconds divided by Target Flight Time in
seconds and the result multiplied by 100 then rounded to the nearest 0.1%. If
the result is greater than or equal to 100, subtract 100 from it. Otherwise,
subtract the result from 100.

For example:

Flight 1 Actual = 95.2 seconds,
Target = 120 seconds

95.2 / 120 x 100 = 79.333… which is rounded to 79.3

Since 79.3 is less than 100, subtract 79.3 from 100 to get the Time score of
20.7

Flight 2 Actual = 144.8, Target = 120 seconds

144.8 / 120 x 100 = 120.666… which is rounded to 120.7

Since 120.7 is greater than 100, subtract 100 from 120.7 to get the Time score
of 20.7

Flight 3 Actual = 120, Target = 120 seconds

120 / 120 x 100 = 100 which is rounded to 100.0

Since 100 is equal to 100, subtract 100 from 100 to get the Time score of 0

Distance: Measured from the nose of the model to the target spot in
meters. If your entry is more than 50 meters from the target, or if you catch
or interfere with your entry’s landing, the Distance score is 100.

For example:

Flight 1 Distance is 50 meters,
score is 50

Flight 2 Distance is 51 meters,
score is 100

Flight 3 Distance is 49 meters,
score is 49

Add the scores for all three flights:

Flight 1: 20.7 + 50
= 70.7

Flight 2: 20.7 +
100 = 120.7

Flight 3: 0 + 49 =
49

Final score = 70.7 + 120.7 + 49 = 190.4

What Will Disqualify My Entry?

* Your entry will be disqualified if the gliding portion has
a permanently attached streamer or parachute. USMRSC 62.2

* Your entry will be disqualified if you do not maintain
full control of your entry at all times. USMRSC 62.2

* Your entry will be disqualified if, in the opinion of the
contest officials, the glider fails to glide. USMRSC 11.1

* Your entry will be disqualified if its power pod separates
at launch and proceeds into the air under power without the glider. USMRSC 10.3

How About Some Suggestions for New Competitors?

First, learn to fly a radio controlled glider. Start with an
inexpensive park flyer. Here are some links about learning to fly RC:
